This paper explores abatement investment and location responses to environmental policy, which takes the form of emission taxes or tradeable emission permits and subsidies against the costs of abatement investment, under uncertainty and irreversibility. Uncertainty is associated with output...

It has often been asserted that imposition of environmental regulations in the 1970's may be a partial explanation for the productivity growth slowdowns experienced by most industrialized countries during that decade.The contention is that expenses incurred to satisfy these regulations, such as...

We study which policy tool and at what level a majority chooses in order to reduce activities with negative externalities. We consider three instruments: a rule, that sets an upper limit to the activity which produces the negative externality, a quota that forces a proportional reduction of the...

I examine the risk/return tradeoff for environmental investments, and its implications for policy choice. Consider a policy to reduce carbon emissions. To what extent does the value of such a policy depend on the expected future damages from global warming versus uncertainty over those damages,...

Extremely low discount rates play a central role in the Stern Review's evaluation of environmental protection, and this assumption has been criticized by many economists. The Review also stresses that great uncertainty is a critical element for optimal environmental policies. An appropriate...

While economic models have already proven useful to analyze big picture questions about climate policy such as the choice between a carbon tax or cap-and-trade permit system, the 19 chapters in this book show how economic models also are useful to address the many remaining smaller questions...

The MIT Emissions Prediction and Policy Analysis model is applied to synthetic policies that match key attributes of a set of cap-and-trade proposals being considered by the U.S. Congress in spring 2007. The bills fall into two groups: one specifies emissions reductions of 50% to 80% below 1990...

There is widespread agreement among economists – and a diverse set of other policy analysts – that at least in the long run, an economy-wide carbon pricing system will be an essential element of any national policy that can achieve meaningful reductions of CO2 emissions cost-effectively in...

We analyze the distributional and efficiency impacts of different allowance allocation schemes for a national cap and trade system using the USREP model, a new recursive dynamic computable general equilibrium model of the U.S. economy. We consider allocation schemes applied to a comprehensive...

We assess the long-run dynamic implications of market-based regulation of carbon dioxide emissions in the US Portland cement industry. We consider several alternative policy designs, including mechanisms that use production subsidies to partially offset compliance costs and border tax...
